Embodiment Construction

[0018] figure 1 A two-dimensional image collector 100 with matched illumination constructed in accordance with the principles of the present invention is shown. In this device, a two-dimensional image collector 100 is composed of one or more groups of light sources 103 located behind a reflector array 101, and the reflector array 101 is composed of reflectors 105 corresponding to the light sources. In this embodiment, the light sources 103 are arranged in a one-to-one array corresponding to the array of reflectors or any light source 103 has a corresponding reflector 105 . The light source 103 may consist of any light emitting element, such as a light emitting diode (LED) or other light emitting element.

[0019] In operation, after the light emitted from the light source 103 is reflected by the majority of reflectors 105 on the reflective array 101 , an illumination pattern 110 is projected on the target image area. The light source 103 and the majority of reflectors 105 ca...

Abstract

A 2D imaging data collection sensor with matching illuminator. The illuminator comprises an array of light emitting reflectors projecting an illumination pattern onto a target area containing an image to be read. The illumination pattern both serves as visual aiming assistance and provides target illumination. The shape of the projected illumination pattern is generated by an array of reflectors, reflecting light that emanates from an array of light sources. The shape of the individual reflectors, and the arrangement of the reflectors and light sources produce the desired uniformity and shape of the illumination pattern. The target image is sensed by an image sensor, and a micro-controller performs all sensor-setting, image capture, feature extraction, and decoding. Results are sent to a PC via a serial communication port.

Description

technical field [0001] The present invention relates to a portable image acquisition device acquisition method, and more particularly, to a portable image data acquisition device and acquisition method with a matching lighting pattern that not only aids in visual positioning but also provides the illumination required for the target image . Background technique [0002] The portable two-dimensional image collector device has been widely used in various data collection in various fields such as processing industry, service industry and postal express delivery. Such devices are equipped with an illumination component to illuminate the captured image of the object. In addition, a positioning pattern generator needs to be configured to generate various positioning patterns such as dots, crosses, or squares. [0003] Simply adopting the form of dots cannot determine the size of the area required for an effective target, and the cross and frame graphics generated by the laser wi...
